FIELD OF THE INVENTION

The present invention relates to a blockout device, and more particularly to a blockout device for a USB port for preventing contamination, damage or misuse of the USB port when not in use.

BACKGROUND OF THE INVENTION

A USB receptacle is a common data port located on electronics devices, e.g. computers and laptops. With the widespread use of USB ports, it has become a high priority to provide security to the data available via the USB port. Therefore it is important to protect and lock the USB port from contamination, damage or misuse. A USB port lock device is typically inserted in the USB port when the port is not in use to protect the port and to prevent unauthorized access to the port. Prior USB port lock devices engage the openings on the top side of the USB port. However, the prior port lock devices are not compatible with all USB ports since the top side of the USB port doesn't always include openings. Even though prior lock devices cover the USB port, the devices fail to provide a tamper resistant blockout device that securely locks all USB ports.

Thus, it would be desirable to provide an improved tamper resistant blockout device that secures the USB data port when not in use until the blockout device has been removed with a custom removal tool.

SUMMARY OF THE INVENTION

The present invention is directed to a blockout device designed to prevent contamination, damage or misuse of a USB port when not in use. The blockout device includes a locking member, a body member and a shell. The locking member has a bottom and a top. The bottom of the locking member includes a plurality of teeth that engage the USB port when the device is installed in the USB port. The body member has a top, a bottom and sides that define a channel therein. The channel of the body member receives the locking member. The shell includes a cavity that receives the locking member and the body member. The locking member and the body member are positioned within the cavity of the shell when the blockout device is installed in the USB port. The blockout device secures the USB port until the blockout device is removed by a removal tool.

Thus, when the body 84 is installed in the metal shell 110 the removal tool attachment slots 96, 124, respectively, align and the shoulder 98 of the body 84 is positioned in the center slot 126. The shoulder 98 extends above the top 114 of the metal shell 110.

As illustrated in FIG. 5, the slide 62 is positioned in the body 84 in an unlatched position. The projections 76 extending from the sides 74 of the slide 62 engage the front 90 of the body 84 to limit the movement of the slide 62. As illustrated in FIGS. 6 and 7, the metal shell 110 is installed over the body 84 until the removal tool attachment slots 124, 96, respectively, align. FIG. 8 illustrates the slide 62 in a latched position with respect to the body 84 and metal shell 110 of the USB blockout device 60.

FIGS. 9 and 10 illustrate the USB blockout device 60 in an unlatched position with the slide 62 extending past the front 90 of the body and the front end of the metal shell 110. The unlatched USB blockout device 60 is positioned to be installed in the USB port 50.

FIGS. 11 and 12 illustrate the unlatched USB blockout device 60 positioned in the USB port 50. The molded teeth 80 of the slide 62 are positioned on the contact slots 54 of the USB port 50 to secure the USB blockout device 60 to the USB port 50. The molded latch 72 of the slide 62 engages the top 86 of the body 84.

FIGS. 13 and 14 illustrate the USB blockout device 60 in the latched position and fully installed in the USB port 50. When the USB blockout device 60 is latched, the molded latch 72 of the slide 62 extends into the pocket 106 in the body 84. The USB blockout device 60 is secured to the USB port 50. The USB blockout device 60 may only be removed from the USB port 50 via the removal tool 130. As a result, the tamper resistant USB blockout device 60 protects the USB port 50 from contamination, damage or misuse.

FIGS. 15-20 illustrate the removal tool 130 being installed in the USB blockout device 60 and removing the USB blockout device 60 from the USB port 50. The removal tool 130 includes a metal tongue 136 and deflectable arms 140 with inwardly extending projections 142. The metal tongue 136 of the removal tool 130 is inserted in the center slot 126 of the metal shell 110 and under the shoulder 98 of the body 84 into the blockout device 60. As illustrated in FIG. 16, when the removal tool 130 is fully inserted in the blockout device, the metal tongue 136 is positioned under the shoulder 98 and a portion of the removal tool 130 is positioned in the first portion 102 of the channel 100 in the body 84 and the center slot 126 of the metal shell 110.

Also when the metal tongue 136 of the removal tool 130 is installed in the USB blockout device 60, the deflectable arms 140 are positioned at the removal tool slots 96, 124 of the body 84 and the metal shell 110, respectively.

FIGS. 21-24 illustrate a permanent USB blockout device 150. The permanent USB blockout device 150 is installed in a USB port 50 to prevent use of the electronic device via the USB port 50, when desired. The permanent USB blockout device 150 is not intended to be removed from the USB port 50 with a key or any other removal tool. Thus, the blockout device 150 would be installed once to prevent use of the USB port 50.

Similar to the slide 62 discussed above with respect to the USB blockout device 60, the permanent USB blockout device 150 includes a plurality of molded teeth 152. The molded teeth 152 are positioned on the contact slots 54 of the USB port 50. When installing the permanent blockout device 150, the electrical contact plate 52 is deflected downward due to the interference of the molded teeth 152. As illustrated in FIG. 24, after the blockout device 150 is completely installed, the electrical contact plate 52 returns to its original position and blocks the blockout device 150 from being removed.
